.within the car, because such engines are so large that they cannot be placed under the car and because they require more or less attendance which could not be given to them if they were not within the car. Such engines drive the car axles, either through mechanical gearing or by driving a generator which supplies power to motors con nec to the car axles.

and novelQs upporting means for the engine of a motor car, whereby the vibrations of the engine are not transmitted to the main portion of the car platform, which is uslr ally provided with seats for passengers or with a baggage compartment.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part. of this specification. For a better 1 inderstanding of my inven tion, however, reference may be had to the following description taken in connection with the accompanying drawings, in whichlfiigure l is a side elevation of a phrtion of a motor car embodying my invention: Fig. :2 is a section. on the line 2 '2 of Fig. 3; Fig. 3 is a plan view of the car platform of the motor car of Fig. 1, with parts broken away; Fig. 4: is a section on the line 4 4 of Fig. 3; and Fig'S is a section on theline 5 5 of Fig. 3.

Referring to the drawings, 6 is a motor car constructed in accordance with my in vention in which the car platform is di- "viided into twoporti'ons 7 and 8, the upper surfaces ofzwhich may be substantially in the same plane. The portion 7 of the car platform has mounted thereon the engine 9, which develops power for driving the car. This portion 7 of thecar platform is supl i i GRINDIL, 1

etion has for its object a new pivotally mounted on the car trucks ,10, only one of which is illustrated. I preferably provide an elastic or spring support for the portion 7, of the car platform, which support is separate from the support of the main portion 8 of the car platform, and in the particular form shown in the drawings, this support is on. the car axles 11 and independent of the car truck 10.

The car truck 10 has side frames 12 which are elastically supported by means of springs 13 on journal boxes 14 for the car axles 11 in the well-known manner. The car truck has transoms 15 connecting the side frames 12. These transoms support a spring 16 which in turn supports the joint 17, which I have illustrated as a ball and socket joint. The main portion 8 of the car platform rests on side members 18 which are connected together by cross members 19, only one of which is shown. The ball por-- tion of the joint 17 is fastened to the cross member 19 shown, whereby the main portion 8 of the car platform is pivotally mounted on the car truck 10.

The portion 7 of the car platform, on which the engine 9 is mounted, is elastically supported on members 20 by u'ieans of leaf springs 21 and coil springs 22. The members 20 move in suitable guideways and bear on the car axles 11.

The engine 9 is shown as driving an electrical generator 23 which. supplies power to motors (not shown) which drive the car axles 11. The engine is located in the in-. terior. of the car proper as explained above and is accessible from all sides.

'Since the portion 7 of the car platform is mounted on the car axles, it moves with them, and consequently follows the curves in the trackowith the truck 10, but as the main portion 8 of the platform is pivoted on. the car truck 10, the two portions of the car platform rotate relatively to one another when the car is moving around. a curve. The edges 24 and 25 of the portions 7 and 8 of the car platform which lie trans versely to the direction of travel of the car,

are circular in shape, the center of the cirlie ' diaphragm 29.

cle being the joint 17. The lateral edges of the portion 7 are arranged at such a distance from the corresponding edges of the main portion 8 of the car platform so as to permit the necessary motion between the portions 7 and 8. The gaps between the edges 24 and 25 are packed with labyrinth packin s 28, and the gaps betweenthe lateral ecfges of the two portions of the car platform are covered with a diaphragm 29 of leather or the like. Steps 30 protect the Rollers 31 are carried by the framework which supports that portion of the car platform on which the engine 9 is-mounted and roll on arc-shaped members 32 arranged concentrically with the edges 24 and 25. These rollers help to support the portion .7 of the car platform.

I desire it to be understood that my'iir vention is not limited to the particular construction shown and described, and I aim in the appended clai ns to cover all modifications which do not depart from the spirit and scope ofmy invention.

What I claim as new and desire to secure by Letters Patent of the United States, is,- 1. In a motor car, an engine developing power for driving said car, a car platform comprising a main portion and a portion on which said engine is mounted, a car truck on which said main portion of the car plat-. form is pivotally mounted, and means for supporting said portion of the carplatform on which said engine is mounted separately from said main portion of the car platform so-that the vibrations of the engine are not transmitted to said main portion of the car platform.

2. In a motor car, an engine developing power for driving said car, a car platform comprising a main portion and a portion on which said engine is mounted, means for pivotally mounting said main portion of the car platform, and means for supporting said portion of the car platform on which said engine is mounted separately from said main portion of the car platform so that the vibrations of the engine are not transmitted to said main portion of the car platform.

3. In a motor car, an engine developing power for driving said car, a car platform, I

comprising a main portion and a portion on which said engine is mounted, a car truck, means for pivotally mounting said main portion of the ear platform on said truck,

and means for elastically supporting said portion of the car platform on which said engine is mounteo separately from said main portion of the car platform, so that the vibrations of the engine are not transwhich said engine is mounted, car axles, a car truck elastically supported on said car axles, means for pivotally mounting said main portion of the car platform on said car truck, and means for supporting said portion of the car platform on which said engine is mounted on said car axles independently'of said car truck.

In a motor car, an engine developing power for driving said car, a car platform comprising a main portion and a portion on which said engine is mounted, car axles, a

car truck elastically supported on said caraxles, means for pivotally mounting said main portion of the car platform on said car truck, a spring support on said axles for said portion of the car platform on which said engine is mounted independent of said car truck.

6. In a motor car, an engine develo ing power for driving said car, a car platform comprising a main portion and a portion on which said engine is mounted, car axles, a car truck elastically supported on said car .axles, means for pivotally mounting said main portion of t e car platform on'said car truck, and means for elasticallysupport ing said portion of the,car platform on which said engine is mounted so that the vibrations of the engine are not transmitted to the main portion of the car platformf In witness whereof, I have hereunto set my hand this 10th day of'May, 1912.
